The "allsky-website" package allows you to display your images on a website, either on your Pi or on another machine. It can optionally add an overlay of constellations and other objects, as well as optional Aurora data from NOAA.
This version of the WebUI works best with Allsky camera software version 0.8.3 or newer.
The installation script for installing on a Pi is documented on the main Allsky GitHub page.
Once installed, there are several configuration variables you'll want to change.
